Narrative

Technical Innovation & Quality Heritage

YTL’s GPRS/4G Cellular Smart Meters offer plug-and-play connectivity using existing global mobile networks. As an innovative manufacturer, Zhejiang Yongtailong has integrated industrial-grade LTE Cat.1/Cat.M1 and NB-IoT modules to ensure reliable data transmission across different cellular generations. These meters eliminate the need for local data concentrators, as each meter communicates directly with the utility's cloud server. This makes them the perfect choice for geographically dispersed installations, such as telecommunication base stations, commercial chain stores, and high-end residential projects. With support for global roaming and multi-band operation, our cellular meters provide high-bandwidth communication for detailed load profiling, real-time power quality monitoring, and instantaneous remote control.

Product Application

  • Telecom Base Station Management
  • Commercial Retail Chain Auditing
  • Remote Industrial Site Monitoring

Telecom Base Station Management

Telecom operators manage thousands of remote towers often powered by multiple sources, including the grid, batteries, and diesel generators. YTL’s 4G smart meters allow for centralized monitoring of energy costs across the entire network. The high-speed cellular link provides real-time alerts if a site loses grid power or if a generator fails to start. By analyzing the load profiles remotely, operators can optimize their battery backup strategies and detect energy theft or equipment malfunctions instantly, ensuring maximum uptime for critical communication infrastructure.

Commercial Retail Chain Auditing

Perfect for retail companies with hundreds of small shops spread across a country. Since these shops are scattered, installing a local RF or PLC network is not feasible. Each 4G meter acts as its own gateway, sending energy data directly to the corporate headquarters. This allows management to compare the energy efficiency of different branches, automate bill payments, and detect if air conditioning systems are left running after hours, leading to massive energy savings across the entire corporate portfolio.

Remote Industrial Site Monitoring

Ideal for oil and gas pipelines, water pumping stations, and mining equipment located in areas without local IT infrastructure. As long as there is a cellular signal, these meters can provide utility-grade measurement and remote control. The 4G bandwidth allows for the transmission of high-resolution data, including voltage waveforms and peak demand records, which are essential for engineers to troubleshoot power quality issues at distant sites without the need for expensive and time-consuming site visits.

Product Advantages

Zero Infrastructure Setup

Requires no local gateways, concentrators, or specialized wiring. Simply insert a SIM card and the meter is ready to communicate with your management software.

High-Speed Data Throughput

The 4G/LTE bandwidth allows for the collection of granular load profiles and complex power quality data that would be impossible over narrower wireless bands.

Ubiquitous Connectivity

Leverages the massive global investment in cellular networks, ensuring that your smart metering system can be deployed almost anywhere in the world with ease.

Frequently Asked Questions

  • Q: Does it support eSIM?

    A: Yes, many of our 4G models can be equipped with an eSIM at the factory, eliminating the need for physical SIM card management in the field.

  • Q: What happens if the 4G signal is weak?

    A: Our meters feature fallback capabilities (e.g., falling back to 2G/GSM) and can be fitted with an external high-gain antenna to improve reception in difficult areas.

  • Q: How much data does the meter use per month?

    A: For standard hourly reading, data usage is very low (less than 5-10MB/month), making it compatible with affordable IoT data plans.

  • Q: Can I change the APN settings?

    A: Yes, APN and other network credentials can be configured locally via the optical port or remotely through SMS commands and DLMS protocols.

  • Q: Is the connection persistent?

    A: It can be configured for always-on connection or "wake-up" mode to save energy, depending on whether you need real-time relay control.
